It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , the H8S/2268F MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users has the processing power and integration needed for applications such as improved electric power meters and more capable wireless devices and portable home appliances Hitachi Semiconductor (America) Inc. today introduced the H8S/2268F microcontroller (MCU), expanding its popular H8S series of top-end 16-bit MCUs. The H8S/2268 combines a fast 16-bit CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. core up to 20 megahertz One million cycles per second. See MHz. MegaHertz - (MHz) Millions of cycles per second. The unit of frequency used to measure the clock rate of modern digital logic, including microprocessors. (MHz) with an on-chip 256-Kilobyte (KB) Flash memory, LCD controller/driver, DTMF (Dual-Tone MultiFrequency) The type of audio signals that are generated when you press the buttons on a touch-tone telephone. See also DMTF. DTMF - Dual Tone Multi Frequency (dual-tone multiple-frequency *1) output circuit, and other peripherals. The low-power device is a cost-effective, single-chip solution for designs that need nonvolatile data storage, LCD numeric/symbol display, and/or a sine wave A continuous, uniform wave with a constant frequency and amplitude. See wavelength.  A Sine Wave _title> Sine wave generator that outputs specific frequencies determined by buttons on a panel. While providing higher functionality and a variety of peripheral functions, the H8S/2268F also enables shorter turn around times for system designs using its on-chip Flash memory. Typical applications include electric power meters, wireless devices, portable home appliances such as silicon audio devices and health equipment. Many useful built-in peripheral functions To enable cost-effective single-chip implementations for such applications, the H8S/2664F provides a rich array of additional peripheral functions, besides the Flash and LCD and DTMF functions. A 2-channel I2C bus (Inter-IC bus) A two-line bus that is widely used to connect chips together on a printed circuit board. Also called the "I-squared-C bus" and developed by Philips in the 1980s, it is used as a control bus for every variety of chip from sensors to microprocessors. interface and 3-channel asynchronous serial communication Asynchronous serial communication describes an asynchronous transmission protocol in which a start signal is sent prior to each byte, character or code word and a stop signal is sent after each code word. interface allow communication with devices that use various serial interface specifications. The MCU has a 3-channel 16-bit timer, 4-channel 8-bit timer, and 4-channel 8-bit reload (1) To load a program from disk into memory once again in order to run it. Reload is entirely different than reinstall. Reinstall means that you have to run the install program from a CD-ROM or floppy disk and perform the installation procedure over again. timer, as well as a 2-channel watchdog timer A clock circuit that keeps counting from a set number down to zero. If the event it is monitoring occurs before it reaches zero, it resets to the starting number and starts counting down again. that can be used as a real-time clock A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic timer. Its peripheral set also includes a 10-bit 10-channel A/D converter (Analog/Digital converter) A device that converts continuously varying analog signals from instruments and sensors that monitor conditions, such as sound, movement and temperature into binary code for the computer. , 8-bit 2-channel D/A converter (Digital/Analog converter) A device that converts digital code into analog signals. The most common applications are for generating sound and video. The D/A converter may be contained on a single chip or can be one circuit within a chip. Contrast with A/D converter. , and 32-kHz sub-oscillator. RAM size is 16 KB. The H8S/2268F's DTMF function generates frequencies using 400-kHz clock and allows the selection of combined or separate row and column outputs. The chip's 256-KB Flash memory uses single-power-supply programming/erasing. The Flash enables control programs and system adjustment data to be rewritten even when the MCU is installed on a circuit board, for shorter system development times and easy product updates. The MCU's LCD controller/driver interfaces to a display device with 40 segments and 4 common lines. An on-chip 3x step-up circuit allows LCD display at a low voltage. Segment output pins that aren't used to drive an LCD can be used as I/O ports in 8-pin units. MCU produces less radiated noise An on-chip voltage step-down circuit allows the H8S/2268F to operate internally at 3 V using a 5-V external power supply. This lower internal voltage greatly reduces radiated noise. All I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output pins have a 5 V interface, so the MCU can be used with 5-V external peripheral devices. Development tools for system design Customers can use the many existing H8-series software tools (a C compiler, assembler, linkage editor, librarian, simulators, debuggers, and more) as a development environment. A variety of emulators, including the Hitachi E6000 real-time emulator, are also available as hardware support tools for the H8S/2268F MCU. Notes: 1. DTMF (Dual Tone Multiple Frequency) output: This function generates sine waves of two specific frequencies corresponding to individual buttons, in the row (horizontal) direction and column (vertical) direction of a matrix represented by a panel comprising numerals and symbols (0 to 9, #, and * ) on a telephone, for example, and outputs these sine waves in combination.
